Can someone tell me what this is?

I use SpyHunter 4 from Enigma Software for anti-malware protection. Once in a while, after I scan, I get a notice that this:

f:\f0db983a9dbb741cb2\mpsigtubs.exe

is unrecognized, and would I like to allow it or block it. I block it each time, but I still get the query from time to time.

I've done a search of all drives and files using *.exe and it never comes up. I do have an F drive; its an external hard drive that I use for backing up files.

Any ideas or suggestions?

Thank you,

TRS

The old Thread below might help with the issue ...


What is MPSigStub and can it be safely deleted?
